Description

BACKGROUND
1. Technical Field
The present disclosure relates to server centers, and particularly to a server center with effective heat dissipation.
2. Description of Related Art
A server center generally includes a rack and a plurality of servers stacked on the rack. When the servers are working, they generate a large amount of heat, and therefore effective heat dissipation is necessary.
A typical heat dissipating system provided to the server center includes a fan, and an airflow tunnel connecting the fan with the servers. Airflow generated by the fan flows through the airflow tunnel and through the servers, and is expelled to an outer environment, whereby heat generated by the servers is dissipated. However, sometimes some of the servers are not working, and the airflow generated by the fan still flows through these servers. This wastes energy.
What is needed, therefore, is a server center which can overcome the above-described problems.
BRIEF DESCRIPTION OF THE DRAWINGS
Many aspects of the present embodiment(s) can be better understood with reference to the accompanying drawing. The components in the drawing are not necessarily drawn to scale, the emphasis instead placed upon clearly illustrating the principles of the present embodiment(s). Moreover, in the drawing, like reference numerals designate corresponding parts throughout the whole view.
The drawing is a schematic view of a server center in accordance with an embodiment of the disclosure.
 DETAILED DESCRIPTION
Referring to the drawing, a server center in accordance with an embodiment of the disclosure is shown. The server center comprises a server room 10, a plurality of servers 12, a heat dissipating system 20, a plurality of temperature controlling devices 30, and a power controlling device 40. The servers 12 are disposed in the server room 10 and aligned with each other.
The heat dissipating system 20 comprises an airflow tunnel 22, and an exhaust fan 24 connected to the airflow tunnel 22. In this embodiment, the exhaust fan 24 is a dual standby exhaust fan. The airflow tunnel 22 comprises a main tunnel 220, and a plurality of branch tunnels 222 respectively extending from the main tunnel 220. The main tunnel 220 is fluidly connected to the exhaust fan 24, and the branch tunnels 222 are correspondingly fluidly connected to the servers 12. In other words, the servers 12 are respectively disposed at airflow inlets of the branch tunnels 222 of the airflow tunnels 22, and the exhaust fan 24 is disposed at an airflow outlet of the main tunnel 220 of the airflow tunnel 22.
Each of the temperature controlling devices 30 comprises a temperature sensor 32 electrically connected to a corresponding server 12, and an airflow valve 34 mounted in a corresponding branch tunnel 222. The temperature sensor 32 is used for detecting a temperature of the corresponding server 12. Airflow drawn by the exhaust fan 24 flows from the corresponding server 12, through the airflow valve 34, and then through the corresponding branch tunnel 222 and the main tunnel 220 to an outer environment.
Each temperature sensor 32 is electrically connected to a corresponding airflow valve 34. The temperature sensor 32 is used for controlling the corresponding airflow valve 34 to permit air from the corresponding server 12 to enter the corresponding branch tunnel 222 or bar (block) air from the corresponding server 12 from entering the corresponding branch tunnel 222, according to the temperature obtained from the corresponding server 12. In particular, the temperature sensor 32 reads a temperature of the corresponding server 12, and sends a corresponding signal to the corresponding airflow valve 34. In more detail, when the temperature of the corresponding server 12 is lower than a predetermined threshold value, the corresponding airflow valve 34 is controlled to be closed; and when the temperature of the corresponding server 12 is equal to or higher than the predetermined threshold value, the corresponding airflow valve 34 is controlled to be opened.
The power controlling device 40 electrically connects the servers 12 with the exhaust fan 24. The power controlling device 40 comprises a data acquisition member 42 and a controlling member 44. The data acquisition member 42 is used for reading a power consumption of the servers 12, and sending a corresponding signal to the controlling member 44. The controlling member 44 is used for controlling an operating voltage of the exhaust fan 24 according to the power consumption of the servers 12, thereby controlling a rotation speed of the exhaust fan 24. In detail, when the power consumption of the servers 12 is equal to or higher than a predetermined threshold value, the rotation speed of the exhaust fan 24 becomes fast; and when the power consumption of the servers 12 is lower than the predetermined threshold value, the rotation speed of the exhaust fan 24 becomes slow, whereby a power consumption of the exhaust fan 24 can be controlled according to the power consumption of the servers 12.
It is to be understood, however, that even though numerous characteristics and advantages of the present embodiment(s) have been set forth in the foregoing description, together with details of the structures and functions of the embodiment(s), the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
